I have a flush fit insert. I also have an IR and I'm wondering where to read from on the unit as I'm concerned about over firing. As I'm sitting in front of the insert now, aiming at the coal bed it reads 610. Aiming through the top vents at the only view I can get of the top reads 360. It's the front 2 inches of the top as seen through the vents.
So where should I be reading?
